The effect of mesoscopic noise source on surface roughening behavior was studied. For this study, near-normal, 1.8 MeV bombardment of the metallic glass, Zr65Al7.5Cu27.5 was considered. It was found that high-energy irradiation leads to surface roughening mechanisms that operate on a larger length scale than sputtering, and this dramatically affects the surface morphology. Furthermore, it was observed that smoothing of rough amorphous alloys occur by viscous flow for irradiations where nuclear rather than electronic stopping is predominant.
